Subaru Reliability: Best Used Models, Years to Buy, Problems & Lifespan

Are Subarus reliable used cars? Generally, yes. Subaru has earned a strong reputation for durable engines, capable all-wheel-drive systems and vehicles that can provide many years of dependable service. Models such as the Forester, Outback and Impreza are particularly appealing to buyers who want practical transportation with good traction in poor weather.

However, not every Subaru model year has the same reliability record. Older head-gasket problems, excessive oil consumption in certain engines and continuously variable transmission (CVT) concerns have affected some vehicles. Fortunately, many later models have improved considerably.

This guide compares the best used Subaru models, identifies promising years and those deserving closer inspection, explains important engine and transmission differences, and helps you decide which Subaru makes the most sense for your needs.

A note about common problems: Throughout this guide, "common problems" refers to recognized or frequently reported issues worth checking when shopping for a used Subaru. It does not mean that most vehicles experience these problems. Many affect only a minority of vehicles, and plenty of owners never encounter them.

Or, Looking For "New"?

If you're also considering a new Subaru, you may want to come back to this and take a look at a handy technique that identifies the dealer in your area most ready to make price concessions.

Are Subarus Reliable Used Cars?

Yes. Subaru is generally a reliable brand, and a well-maintained used Subaru can be an excellent purchase. The company's naturally aspirated four-cylinder engines, symmetrical all-wheel-drive systems and practical vehicle designs have helped many owners accumulate substantial mileage.

Subaru also benefits from sharing engines, transmissions and other components across several models. Once a mechanical design has been refined, those improvements can benefit multiple vehicles.

Consumer Reports has consistently placed Subaru among the stronger brands for predicted new-car reliability in recent surveys. However, ratings for new vehicles do not automatically describe the dependability of a 10- or 15-year-old used Subaru.

For older vehicles, the particular engine, transmission, model year and maintenance history matter considerably more than the brand's overall reputation.

One important distinction is that Subaru's all-wheel-drive system is generally a strength, but it adds components and maintenance considerations compared with a typical front-wheel-drive car. Tires should be closely matched in size and wear, and drivetrain servicing should not be neglected.

Subaru Reliability at a Glance

These are broad used-car buying assessments, not numerical reliability ratings. Individual model years, engines, transmissions and maintenance histories can change the outlook substantially.

How Many Miles Can a Subaru Last?

A well-maintained Subaru can reasonably reach 150,000–200,000 miles, and some exceed 250,000 miles. However, those figures are possibilities rather than guaranteed lifespans.

The Forester, Outback, Impreza and Legacy are all capable of substantial mileage. The biggest factors are engine condition, transmission health, maintenance history, driving conditions and whether expensive repairs have already been addressed.

A Subaru that reaches 180,000 miles with a healthy engine and transmission may still have useful life remaining. Conversely, a poorly maintained vehicle with 90,000 miles can be a much riskier purchase.

On higher-mileage Subarus, pay particular attention to cooling-system condition, oil consumption, transmission operation, suspension components, wheel bearings and corrosion.

What Are the Best Used Subaru Models to Buy?

For most buyers, the Forester, Outback, Impreza and Crosstrek deserve the most attention. They combine practical designs, strong all-weather capability and generally favorable reliability records when the right years are selected.

The Forester is an especially good choice for buyers who want excellent visibility, useful cargo space and easy access. The Outback offers more highway comfort and room for luggage, while the Impreza provides many of Subaru's advantages at a lower purchase price.

The Crosstrek is an appealing alternative for buyers who want something smaller and easier to park than a Forester.

The Legacy is worth considering for shoppers who prefer a traditional sedan. The Ascent provides more passenger capacity, but early examples require greater care. Performance models such as the WRX and BRZ should be evaluated with particular attention to previous ownership and driving habits.

Pricing

Knowing which Subaru model years to concentrate on is step 1. Step 2 is knowing how to actually get an excellent used Subaru price.

Also, getting a strong trade-in allowance usually has the biggest impact on your final price. See KBB versus Edmunds Appraisals - Which Is Better to get accurate and fair trade-in values before negotiating with a dealer.

Which Subaru Engines and Transmissions Are Most Reliable?

Subaru's mechanical history is important because many of its engines and transmissions appear in several different models.

Subaru EJ25 2.5-Liter Boxer Engine

The older EJ25 2.5-liter horizontally opposed four-cylinder engine powered numerous Forester, Outback, Legacy and Impreza models. It can be durable, but certain versions became known for head-gasket leakage.

Not every EJ25 develops a head-gasket problem, and some vehicles have already received repairs. Buyers should check for coolant loss, external oil leaks, overheating and evidence of previous head-gasket work.

Subaru FB20 and FB25 Boxer Engines

The FB20 2.0-liter and FB25 2.5-liter naturally aspirated boxer four-cylinder engines replaced older designs in many Subaru models.

These engines generally provide good everyday reliability, but certain early-production versions were associated with excessive oil consumption. Subaru's historical oil-consumption settlement covered specified vehicles and production ranges, not every vehicle from the listed years.

Later examples are often preferable, especially when oil changes have been performed consistently and there is no evidence of abnormal consumption.

Subaru FA20 and FA24 Turbocharged Engines

The FA20 2.0-liter and FA24 2.4-liter turbocharged boxer four-cylinder engines appear in performance-oriented Subaru models and certain SUVs.

They offer stronger acceleration but demand careful maintenance. Buyers should be especially cautious about modified engines, neglected oil changes and vehicles subjected to repeated hard driving.

Subaru Six-Cylinder Boxer Engines

Subaru's older 3.0-liter and 3.6-liter horizontally opposed six-cylinder engines have earned a generally favorable reputation when properly maintained.

They are appealing to buyers who want smoother performance without a turbocharger, although fuel economy is lower and some repairs can be more expensive because of the engine layout.

Are Subaru CVT Transmissions Reliable?

Subaru's Lineartronic continuously variable transmission uses a variable-ratio design rather than conventional fixed gears. It provides smooth operation and helps fuel economy, but some earlier applications experienced problems.

Subaru extended CVT warranty coverage to 10 years or 100,000 miles for certain 2010–2015 Legacy, Outback, Impreza, Crosstrek, Forester and WRX vehicles. That historical extension should not be interpreted as coverage that remains active today.

Many Subaru CVTs operate reliably for high mileage. Nevertheless, a used-car inspection should include checking for unusual noises, hesitation, shuddering, delayed engagement, fluid leaks and transmission warning lights.

For any Subaru, the actual maintenance history and condition of the transmission are more important than assumptions based solely on its design.

Final Verdict: Is a Used Subaru a Good Car to Buy?

Yes. A carefully selected used Subaru is often an excellent purchase. The brand offers a compelling combination of all-weather traction, practical interiors, comfortable driving characteristics and generally strong long-term reliability.

For most buyers, the Forester, Outback, Impreza and Crosstrek provide the best balance of reliability, usefulness and ownership costs. The Legacy is an appealing sedan alternative, while the Ascent, WRX, BRZ and Solterra serve buyers with more specialized needs.

The biggest mistake is assuming that every Subaru is equally dependable simply because the brand has a good reputation. Certain older engines, early CVT applications and specific model years deserve closer scrutiny.

Choose a Subaru with a healthy engine and transmission, complete maintenance records, no unresolved safety recalls and a satisfactory independent inspection. Do that, and a used Subaru can provide many years of dependable transportation.
